It is costly to buy even a cheaper one. here at my place cost only rm40 for every check-up and the last 2 years I need to use it only once.

Yup, costly to own unless you use it often and do your own work. Then worthwhile investment.
In addition sometimes interpreting the code not so straightforward.
1st example, had a car with alarm siren going off randomly. Sent to mechanic, used generic OBD reader - no error codes detected. Sent to service center, they hook up to their reader, threw up error code saying fault with siren. Recommendation - replace siren RM900!. No thanks, paid RM80 for OBD scanner service and took car back home. Finally I fixed it myself without needing to replace siren with RM0 cost. Problem was voltage issue.
2nd example, check engine came on. Read the codes - front oxygen sensor fault. My mechanic quite experienced with this so he just changed the plugs, changed the oil and walla check engine light issue resolved. If other shops, you may just be billed for a new $$$ oxygen sensor with problem not solved.
Now, if they had OBD device that could not only read but reprogram the ECU like the dealer have, that I may buy if the price is right.
